^o Original Descriptions of Achatinella. 



2io. Achatinella depicta Baldwin. 



A. depicta Iiald. P. Acad. Phil., 1895, p. 22S, pi. xi, figs. 33-35. 



Shell sinistral, sometimes slightly perforate, rather thin, elon- 

 gately conical, apex subacute; surface shining, striated with very 

 delicate growth lines; nuclear whorls smooth; color light yellow 

 or reddish yellow, plain or marked with numerous black, anasto- 

 miziug veins; apex almost black in some examples; whorls 7, 

 faintly margined above, somewhat convex, suture distinctly im- 

 pressed ; aperture a little oblique, oval, white or pinkish, the 

 outside markings visible within; peristome simple, very thin; colu- 

 mella white, subplicate, tortuous, abruptly terminating in a thin 

 lamellar plait. Length 15 1-2, diam. 6 1-2 mm. 



Animal extended in motion shorter than the shell. Mantle 

 very light brown. Foot above and below almost white. Tentacles 

 short, light brown. 



This species is allied to A. alexandri Newc, from the Island 

 of Maui, and to A. rcmyi Newc, from the Island of Lanai, but 

 differs from both in the color and habits of the animal. — Bald.

REMYI GROUP. 

 211. Achatinella remyi Newcomb. 



A. remyi Newc. Am. Jour. Conch., ii, 1S66, p. 215, pi. xiii, fig. 13. 



Shell accuminately elongate, striae numerous, well defined, 

 obliquely longitudinal; whorls 7, rounded, minutely margined 

 above or plain; suture rather deep; aperture subovate; columella 

 slightly callous, with a terminal lamellar plait ; color salmon, 

 painted with numerous zigzag black lines continuous from the 

 summit to the base of the shell; lip margined within with reddish- 

 purple. Long. 14/20, lat. 6/20 poll. 



Remarks. This species is of great rarity, only a few speci- 

 mens having been collected. It is not so robust a shell as the pre- 

 ceding, with which it had affinities, as also with sanguinea and 

 picta. The measurements from adult specimens give the following 

 results, viz : A. picta, 19/20X8 1-2/20 ; A. tetrao, 15/20X9/20; 

 A. sanguinea 18/20X8/20; A. remyi, 14/20X6/20. — Newc.
